Topography of Surface and Spinal Deformity
The Department of Photogrammetry Warsaw University of Technology has been involved in use of in industrial and biomedical applications moiré topography for over ten years. Most of this effort has been inspired by a particular application, namely, the determination of the surface topography of the human back for the detection and diagnosis of spinal deformity. The moiré technique is recommended ...
متن کاملMulticenter Comparison of 3D Spinal Measurements Using Surface Topography With Those From Conventional Radiography.
INTRODUCTION In pediatric spinal deformity the gold standard for curve surveillance remains standing full-column radiographs, but repeated exposure to ionizing radiation motivates us to look for nonradiographic solutions. This study tests a modern system of surface topography (ST) to determine whether it is reliable and reproducible. METHODS Patients from 6 pediatric spinal deformity clinics ...
متن کامل3D Surface Topography from Intensity Images
This paper demonstrates how a new shape from shading scheme can be used to extract topographic information from 2D intensity imagery. The shape-from-shading scheme has two novel ingredients. Firstly, it uses a geometric update procedure which allows the image irradiance equation to be satisfied as a hard-constraint. This not only improves the data-closeness of the recovered needle-map, but also...
متن کاملEvaluation of a Novel Spine and Surface Topography System for Dynamic Spinal Curvature Analysis during Gait
INTRODUCTION The assessment of spinal deformities with rasterstereography can enhance the understanding, as well as can reduce the number of x-rays needed. However, to date this technique only allows measurements under static conditions. Since it would be of great value to be able to also analyze the spine in dynamic conditions, the present study evaluated a novel rasterstereographic system. ...
متن کاملQuantitative Characterisation of Surface Finishes on Stainless Steel Sheet Using 3d Surface Topography Analysis
Since the growth and improvement of digital computers there have been significant changesin the way that surfaces can be measured and viewed. The ‘parameter rash’ that occurred intwo-dimensional measurements [1] is being avoided by standardising 3 dimensionalparameters before the techniques have wide spread use. Huddersfield University is headingmuch of this standardisation work...
